How do I center a text with the python PIL library?

Question

so guys, I did an event on_member_join with an image using the Pillow library, and I’m looking for help to make the PIL calculate the text size and center it according to the user’s name, can help me?

    ```url = requests.get(member.avatar_url_as(format="png"))
    avatar = Image.open(BytesIO(url.content))
    avatar = avatar.resize((210, 210));
    bigsize = (avatar.size[0] * 2,  avatar.size[1] * 2)
    mask = Image.new('L', bigsize, 0)
    draw = ImageDraw.Draw(mask)
    draw.ellipse((0, 0) + bigsize, fill=255)
    mask = mask.resize(avatar.size, Image.ANTIALIAS)
    avatar.putalpha(mask)

    saida = ImageOps.fit(avatar, mask.size, centering=(0.5, 0.5))
    saida.putalpha(mask)

    fundo = Image.open('cogs/img/bem-vindo.png')
    fonte = ImageFont.truetype('cogs/img/college.ttf',42)
    
    escrever = ImageDraw.Draw(fundo)
    escrever.text(xy=(230,345), text=str(member),fill=(0,0,0),font=fonte)
    fundo.paste(saida, (357, 39), saida)

    fundo.save("cogs/img/welcome.png")```

only that it only stays in a certain location, and wanted to center it in space (https://cdn.discordapp.com/attachments/738572311107469354/767727707710160896/unknown.png)
